CROSS-REFERENCE TO RELATED APPLICATION

This application is a U.S. National-Stage entry under 35 U.S.C. § 371based on International Application No. PCT/EP2019/065697, filed Jun. 14,2019, which was published under PCT Article 21(2) and which claimspriority to German Application No. 10 2018 209 894.8, filed Jun. 19,2018, which are all hereby incorporated in their entirety by reference.

TECHNICAL FIELD

The present application concerns an oxidative hair-lightening orhair-dyeing product in cream form, a kit containing that hair-lighteningor hair-dyeing product and a hair-lightening or hair-dyeing processusing that hair-lightening or hair-dyeing product.

BACKGROUND

So-called oxidation brightening agents are used to lighten or bleachhair. So-called oxidation dyes are used for permanent, intensivedyeing's with corresponding fastness properties. Such dyes usuallycontain oxidation dye precursors, so-called developer components andcoupler components. Under the influence of oxidizing agents oratmospheric oxygen, the developer components form the actual dyes amongthemselves or when coupled with one or more coupler components. Theoxidation dyes are exemplified by excellent, long-lasting dyeingresults. For natural looking dyeing's, however, a mixture of a largernumber of oxidation dye precursors (OFV) must usually be used.Frequently, hair lightening or hair dye products also contain at leastone direct dyestuff (DZ) to nuance or matt unwanted shades of themelanin decomposition products.

In most cases, oxidative hair whitening and hair dyeing products have analkaline pH value for stabilizing the dye precursors during storage andfor accelerating the reaction during oxidative application, which isadjusted with alkalizing agents such as alkanolamines, ammonia orinorganic bases.

To form the dye, the alkaline dye component is usually mixed with anaqueous hydrogen peroxide solution to form a homogeneous cream or geland then applied directly to the hair to be dyed. To lighten the hair bythe oxidative breakdown of the natural hair dye melanin, the alkalinelightening component is usually mixed with an aqueous hydrogen peroxidesolution to form a homogeneous cream or gel and applied directlyafterwards to the hair to be bleached. The coloring or lighteningmixture remains on the hair for a period of from about 5 to about 60minutes until the oxidative formation of the dye on the hair or thebreakdown of melanin is completed. The dyeing or brightening mixture isthen washed out.

The above-mentioned oxidation dye precursors (OFV) and alkalizing agentsare usually incorporated in a cosmetically suitable carrier, such as acream. The carrier ensures a homogeneous distribution and sufficientdwell time of the hair brightener or hair dye on the hair. Many OFV arearomatic amine compounds. Some of the commonly used OFV, such asp-toluenediamine or, 5-diamino-1-(2-hydroxyethyl)pyrazole, are onlystable or can be used on a large scale in the form of their salts,especially as sulphate. Their addition thus increases the electrolyteconcentration in the carrier. This can lead to a destabilization of thegel or cream carrier. The carrier of the agent as contemplated hereinmust therefore have a good tolerance to higher electrolyteconcentrations. Furthermore, the carrier must have a viscosity suitablefor the application even after dilution with the aqueous oxidantcomposition. Cream carriers with a too high content of high-melting fatcomponents, such as fatty alcohols, often show a particularly sharp dropin the viscosity of the application mixture compared to the oxidant-freecarrier.

The maximum molecular weight of the polymer depends on the degree ofpolymerization (number of polymerized monomers) and is co-determined bythe polymerization method.

In oxidative hair whiteners and hair dyes for light shades, direct dyesare often used to nuance unwanted reddish tones, which can be caused bymelanin degradation products, or to nuance certain blonde shades.

To obtain a balanced and subtle nuance, the present disclosure may alsoprovide that cosmetic products containing OFV additionally contain atleast one direct dye.

Direct dyes are dyes that are applied directly to the hair and do notrequire an oxidative process to develop the color. Direct dyes areusually nitrophenylenediamines, nitroaminophenols, azo dyes,anthraquinones or indophenols.

Direct dyes can be divided into anionic, cationic, and non-ionic directdyes.

Furthermore, naturally occurring dyes, such as those contained in hennared, henna neutral, henna black, chamomile flowers, sandalwood, blacktea, walnut, rotten bark, sage, blue wood, madder root, catechu andalkanna root can also be used as direct dyes.

As contemplated herein, the term “room temperature” refers to thetemperature in the room in which a person usually uses a hair whiteningor coloring product, i.e. usually a bathroom or hairdressing salon,where the temperature is in the range from about 10-29° C.

Leaving the hair brightening or hair coloring application mixture inprocess step iv) in the hair brightening or hair coloring processes ascontemplated herein or preferred as contemplated herein can also takeplace at at least about 30° C., preferably at from about 30-60° C.,particularly preferably at from about 32-50° C., if the hair is heatede.g. with a heating bonnet or with a radiant heater.

For application to the hair, however, the application mixtureshould have a significantly higher viscosity so that it remains on thehair during the entire application time (in the range of from about 5-60minutes, preferably from about 30-45 minutes) and does not drip down. Adistinction is made between whether the application mixture is preparedby shaking both compositions (M1) and (M2) in an application bottle,from which the application mixture is applied to the hair immediatelyafter mixing with the aid of an application spout as a bottle top(bottle application), or whether the application mixture is prepared bymixing both compositions (M1) and (M2) in a bowl, from which theapplication mixture is applied to the hair with a brush immediatelyafter mixing (brush application).

Production of Application Mixtures and Coloring on Hair

Dyeing gel and developer according to table 2 were homogeneously mixedin the weight ratio 5:2 (5 parts dyeing gel to 2 parts developer). Theapplication mixture thus obtained was applied to strands of human hair(natural white hair, Kerling company) immediately after production(liquor ratio 4 grams of application mixture per gram of hair) and lefton the hair for 30 minutes at room temperature (22° C.). The strandswere then rinsed out and dried with a towel.

To investigate the influence of the cationic polymer content, especiallypolyquaternium-22, the four test compositions listed in Table 9 wereprepared and their viscosities measured. The four test compositions wereeach mixed in a weight ratio of 1:1 with the oxidizing agent compositionaccording to table 2 to the hair brightening application mixture, forwhich the viscosity was also measured.

Cream V1, not as contemplated herein, and its application mixture withthe oxidizing agent composition have viscosities that are slightly toolow for application on the hair and are therefore not optimal.

Cream V2 itself, which is not as contemplated herein, has a viscositythat is practicable for the application. Their application mixture withthe oxidizing agent composition, on the other hand, clearly losesviscosity.

Only through the addition of the cationic polymer (E2, E3) areviscosities achieved which remain largely stable even after mixing withthe oxidant composition, thus enabling optimum application properties.
